Linen or cotton canvas: what is the difference?

Linen canvas is stronger and less likely to warp over time, while cotton canvas feels softer and costs less. Our paint by numbers kits use printed linen canvas, with the design outlines and numbers already marked for you. This gives you a firm surface for painting and helps the canvas keep its shape as you work. Cotton canvas is an alternative if you prefer a softer material or want to reduce the cost, but it is not the canvas we use for our kits.
